• the threshold value is set as a function of a speed of an approaching object 103. For example, a high-speed vehicle is approaching from behind, and the driver of the motor vehicle 101 is warned by changing the appearance of the image on the monitor 104.
• the threshold value is set as a function of visibility of the object 103.
• the object 103 is hidden behind a long curve.
• the transmitted via the car2car communication position is taken into account and combined by means of example detailed map data, so that there is information about the elongated curve.
• the object 103 is detected in the image 201 of the camera 102 of the camera-monitor system 100 by means of object recognition.
• the further control device 109 it is determined by means of the further control device 109, whether the object 103 for the driver of the motor vehicle 101 should already be visible. For example, this is done by means of radar sensors LIDAR.
• the history of how and when the presentation property should be changed and thereby warned is included. For example, when the motor vehicle 101 is moved on a highway, it is possible that no other car, and thus no object 103, will approach for a longer time. Thus, the
• Threshold set comparatively low to give a warning early.
• the driver's concentration is lower than in the case of heavy traffic. For example, if another vehicle relatively promptly follows the previous warning, the next warning could accordingly be less intense or even fail.
• FIG. 3 shows the image 201 of the camera 102 with unchanged display properties according to an exemplary embodiment.
• FIG. 4 shows a modified image 202 according to an exemplary embodiment.
• the modified image 202 is displayed on the monitor 104 in order to alert the driver to the attention-relevant object 103 or to warn.
• FIG. 3 shows the conventional representation of the image 201, in which the camera monitor system 100 selects the presentation properties so as to be able to display as many details of the surroundings 104 as possible.
• the brightness in the area of the headlights of the approaching motor vehicle 103 is reduced.
• the brightness of the monitor 104 is increased.
• the modified image 202 with the changed display properties simulates, for a short time, an aperture that could occur with a conventional side mirror.
• Figure 5 shows the image 201 according to another embodiment example.
• the attention-relevant object 103 is a pedestrian in the area of the motor vehicle 100.
• the display properties are changed such that the modified image 202 shown in the monitor 104 is colored in color.
• a yellow veil is provided in order to point the user of the motor vehicle 101 to the person 103 in the area of the motor vehicle 101 and to warn him / her against this.
• Figure 7 shows the image 201 according to another embodiment example.
• the attention-relevant object 103 is a motorcycle approaching from behind.
• the presentation properties are changed and the modified image 202 is displayed, as shown by way of example in FIG.
• a graphical element 203 is displayed.
• the graphical element 203 is in the embodiment shown, a frame, in particular in a pre-given color, which is displayed on the monitor 104.
• the frame 203 is shown on the outer periphery of the monitor 104.
• the frame is provided in the area of the security-relevant object 103.
• a presentation area 204 is determined in which the security-relevant object 103 is displayed on the monitor 104.
• the image 202 is changed only outside the display area 204 to warn the user of the motor vehicle 101.
• the unchanged image 201 is displayed.
• attention-relevant object 103 shown as detailed as possible. It is avoided that important information is not displayed on the monitor 104 due to the change of the display characteristic, for example, an emergency vehicle's flashing light.
• the different described examples for the change of the presentation properties can be combined arbitrarily.
• the representation outside the display area 204 is colored in color, as explained in connection with FIG.
• the described method as well as the described camera monitor system 100 make it possible to inform the driver of the motor vehicle 101 about dangers without the driver having to look directly at one of the monitors 104. With the help of color or brightness coding, different types of dangerous situations are also communicated. In addition, the dazzling effect of approaching vehicle headlights is avoided ver. The safety for the driver and other persons is thereby increased. It is also possible to inform the driver about movements outside the vehicle 101 in the state, for example, as a theft warning system. Alternatively or additionally, it is possible to warn the driver before getting out of an approaching vehicle. This is triggered for example by a handle to the doorknob.
• the environment 105 is detailed and easily recognizable in the monitor 104. Especially at night, it is possible the display brightness sufficiently reduce. Nevertheless, a warning effect is realized by temporarily changing the display on the monitor 104.
